SUMMARY: Title: Usage of measurer of external performance in trainings of cyclists and triathlonists in Czech republic Made by: Zdeněk Kučera Supervisor: PaedDr. Josef Horčic, Ph.D. Objectives: The main goal of this bachelor thesis is to find out, what is the usage of measurer of external performance for training management. The usage of wattmeter will be analysed among cyclists and triathlonists in Czech Republic. Methods: In my research, which was realized for the purpose of reaching the goal of thesis, was used the survey. The obtained information were sorted and interpreted by graphs. Results: It was found out, that performance measuring according to watts is supported and wattmeter plays an important role among other ways of measuring performance. It is necessary, that using of this tool has to be based on experiences, knowledge and individual access of cyclist. In despite of popularity of wattmeter the other ways of performance measuring are still inconsiderable, especially heart rate is not replaceable. Keywords:Wattmeter, heart rate, cadence, training management.

Title: Verifying the device Cyclus 2 for performance evaluation and training Triathlon Objective: The aim is to verify the suitability of the device Cyclus 2 for triathletes stressful diagnosis and suggest its use for performance evaluation and trénovanosti during RTC. Methods: The work is qualitative in nature with elements of the description and exploration. Results: The result of the work is to create a list of appropriate tests for analyzing training and performance in triathlon and their inclusion in the RTC. Then transfer the user interface device to create and czech manual for its operation in Czech. The most appropriate test for diagnosing trénovanosti and performance in triathlon roundedconsider a test that provides valuable information on growth performance during the annualtraining cycle. Another good test for triathletes is the Wingate test on the ability to work the muscles in the anaerobic mode. Test maximum cadence, maximum strength and CPI test is not stressful for the diagnosis of triathletes too important, but can be used to obtain an overall view of the level of cycling performance. Conconiho test can be used as a simpler butless accurate alternative test round. Keywords: cycling, diagnostics, perseverance

Kovářová, Lenka ; Mráz, František (advisor) ; Černo, Peter (referee)
Title: Testing the Learning of Restarting Automata using Genetic Algorithm Author: Bc. Lenka Kovářová Department: Department of Software and Computer Science Education Supervisor: RNDr. František Mráz, CSc. Abstract: Restarting automaton is a theoretical model of device recognizing a formal language. The construction of various versions of restarting automata can be a hard work. Many different methods of learning such automata have been developed till now. Among them are also methods for learning target restarting automaton from a finite set of positive and negative samples using genetic algorithms. In this work, we propose a method for improving learning of restarting automata by means of evolutionary algorithms. The improvement consists in inserting new rules of a special form enabling adaption of the learning algorithm to the particular language. Furthermore, there is proposed a system for testing of learning algorithms for restarting automata supporting especially learning by evolutionary algorithms. A part of the work is a program for learning restarting automata using the proposed new method with a subsequent testing of discovered automata and its evaluation in a graphic form mainly. Keywords: machine learning, grammatical inference, restarting automata, genetic algorithms

Effect of swimming on the overall triathlon performance in triathlon races World Championships in years 2000 - 2010
Koktová, Veronika ; Kovářová, Lenka (advisor) ; Horčic, Josef (referee)
Title: The influence of swimming part of triathlon the total performance in competitions of world championships 2000-2010. Objectives: The aim is to investigate the influence of the swimming part of the total performance in triathlon in the lost 10 years. Methods: The relation between two variables (times from swimming and the total time of competitions from competitions of world championships 2000-2010 were described with the help of linear regression. Individual years were then compared in a point graph. Results: Our hypothese were confirmmed. It means that the result from the swimming part explains the result from the competition in less than 30%, which means the R2 is smaller than 0,3. We also found, that the influnence of the swimming part on the final result in triathlon has not changed in the last years. The relationship times in the swimming part and total (final) times was closest in 2005 (R2= 0,21). In other years, this dependence is lower, R2 was smaller than 0,07. Keywords: linear regression, longitudinal analysis, performance

A Comparison of heart rate, lactic acid production and swimming speed in a flowing channel and a swimming pool
Kozel, Tomáš ; Horčic, Josef (advisor) ; Kovářová, Lenka (referee)
Name of Work Comparison of heart-rate, lactate levels, swimming speed in streamlined (aerodynamic) channel and swimming pool. Goal of Work To determine whether the same swimming speed affects the heart-rate and blood lactate in exactly the same way, in both the aerodynamic channel and in the swimming pool. To check the velocity of water flowing in a streamlined channel. Method Data collection (blood lactate, values of heart-rate, speed of swimming) will be done first in the swimming pool and then in the streamlined channel, the so-called FLUM. Probands will swim progressively faster in swimming sections of equal length. To obtain lactate levels, the invasive method will be used. Cardiac frequency will be obtained from heart-rate monitors, which each proband will have mounted on the body throughout testing. To verify the speed of flowing water, measuring equipment (propellers) borrowed from the Czech Agricultural University Prague, will be used. Results The work provides information on whether there is a difference in values or internal performance when comparing the speed in swimming pools with the speed in a streamlined channel. If so, the researcher will create a formula to convert the swimming speed in the aerodynamic channel to the speed level in a swimming pool. To create a formula that would...
